SETUP

NAME

SYNOPSIS

DESCRIPTION

setup
is called once from within
linux/init/main.c.
It calls initialization functions for devices and file systems
configured into the kernel and then mounts the root file system.

No user process may call
setup.
Any user process, even a process with super-user permission,
will receive
EPERM.

RETURN VALUE

setup
always returns -1 for a user process.

ERRORS

EPERM

Always, for a user process.

CONFORMING TO

This function is Linux specific, and should not be used in programs
intended to be portable, or indeed in any programs at all.
Since Linux 2.1.121, no such function exists anymore.
The calling sequence varied: it has had a single parameter
void * BIOS
and at other times a single parameter
int magic.
